Found in spiderweb during the day. Could this be the Mayfly - Isonychia?

Leptophlebia
Hi Jon-

Really nice photo. I believe your mayfly male imago to be of genus Leptophlebia. The reason it has only two tails is that its terminal filament (middle tail) appears to have broken off.

 
Right Tail Is Missimg
Hi Jon,

Upon closer examination of the tails on your photo, I now notice that it's actually the right tail which is missing, as the middle tail (terminal filament), which is shorter and of smaller diameter (a characteristic of Leptophlebia) is actually present, but just being held (by a strand of the web) in a position making it appear to be the right tail.

 
Thanks Roger!
Ah, The Black Quill spent spinner. O.K. I'll tie one on for my fellow TU members!

Your website is nicely done. Well worth the visit to:
